Xania Inc. uses a normal job-order costing system. Currently, a plantwide overhead rate based on machine hours is used. Xania's plant manager has heard that departmental overhead rates can offer significantly better cost assignments than a plantwide rate can offer. Xania has the following data for its two departments for the coming year:
Department A | Department B | |
Overhead costs (expected) | $750,000 | $330,000 |
Normal activity (machine hours) | 6,000 | 10,000 |
Required:
- Compute a predetermined overhead rate for the plant as a whole based on machine hours.
- Compute predetermined overhead rates for each department using machine hours. (Note: Carry your calculations out to the nearest dollar.)
- Job 73 used 25 machine hours from Department A and 50 machine hours from Department B. Job 74 used 40 machine hours from Department A and 15 machine hours from Department B. Compute the overhead cost assigned to each job using the plantwide rate computed in Requirement 1. Repeat the computation using the departmental rates found in Requirement 2.
Job 73 Plantwide
| Job 73 Departmental |
Job 74 Plantwide
| Job 74 Departmental |
- Using a Plantwide, if actual machine hours for the year were 17,000 hours and actual overhead costs were $1,100,000, how much was overhead under- or over-applied for the year and how would that affect Cost of Goods Sold when it is closed to that account.
$$_________________________ over-applied/under-applied (circle one)
$$_________________________ Cost of Goods Sold increased/decreased (circle one)
